Abstract

A method of encrypting and transmitting data and a system for transmitting encrypted data (118). The method includes one or more different encryption algorithms, and may include employing different encryption algorithms to achieve multiple levels of encryption. A first encryption algorithm is based upon multiple rearrangements of bits representing data to obtain encoded data. A second encryption algorithm is based upon performing multiple XOR operations on bits representing data so that each data word is at least encoded with previous data words. The system comprises first (204) and second (218) computers and a plurality of communication parameters. The two computers are communicably connected to a network, and the second computer is adapted to route a transmission to the first computer. The transmission includes a data part and a header part (232), both of which are encrypted by the second computer utilizing the communication parameters. The first computer decrypts the transmission utilizing the communication parameters.
